หมอนรองเตียงรูปสามเหลี่ยม

I’ve been using it under my knees every night for the back pain, and the firm foam holds its shape without flattening out by morning. The height actually lets me sleep through the night without tossing and turning.

The incline is just right for reading in bed without my neck cramping, and the foam holds its shape even after a full night of sleeping on it. I’ve used it under my knees for lower back relief too, and it’s honestly been a game changer for both.

The incline is just right for propping up with a book during lazy Sunday mornings, and my back pain has noticeably eased since I started using it under my knees at night. Took a couple nights to get used to the firmness, but now I can't sleep without it.
